crunchy cake

When you slap your significant others ass and it sounds hollow.... basically shes a stick bug

Ex:damn man i didnt know my girl had such a crunchy cake... it must be stale or sumthing cuz it sounded old

Crunchy Nut Fish Cake

When you pull out and cum on the outside of her pussy and throw a handful of granola so it sticks.

Nancy said her favorite food was oat meal, so I nutted on her and gave her a Crunchy Nut Fish Cake.
